Some Tests of Alternative Accessibility Measures: A Population Density Approach
比较了九种可达性度量方法,通过回归分析和非嵌套检验发现,重力型可达性度量在解释人口分布方面表现最佳,而最常用的距离倒数加权机会度量未被其他方法显著超越。
This paper presents nine alternative accessibility measures and evaluates their usefulness in explaining population distribution. It first evaluates these measures by using the criterion of maximum explanatory power in standard regression analysis. It then performs non-nested tests on these nine measures. The paper concludes that gravity-type accessibility measures generally perform better than other measures. The most commonly used measure, size of opportunity weighted by the reciprocal of distance, is not statistically surpassed by any other measures. Cumulative opportunity within the average commuting distance and the distance to the central business district are the poorest accessibility measures.
